Specification of Letters Patent.

Patented nec. 17, 19o?.

application tiled September 13.1907. Serial No. 392.678.

To all whom it may concern:

Be it known that 1, JOSEPH A. BnoH'roLD, a citizen of the United States, residing at New York city, Brooklyn, county. of Kings,

and State of New York, have invented new and `useful Improvements in Hedge-Trimother thicker portions oi the hedge.

In the accompanying drawing: Figure 1 is a plan view of my improved hedge trimmer; Fig. 2 a side elevation thereof; Fig. 3 a section online 3 3, Fig. 1; Fig. ian enlarged section on lifne 4 4, Fig. 1, and Fig. 5 a detail of one of the gear wheels.

The hedge trimmer comprises essentially a pair of stellated cutting blades 10 turning on a common spindle 1 1. Both edges of each of the star-points are sharpened 4to constitute4 knives. Blades 10 are straddled by a pair of forked Shanks 12 turning on spindle 11y and terminating in handles 13 provided with guards 14. To each fork12 is secured, by bolt 15, a segmental rack 16 passing through the other fork and into which meshes a pinion 17fulcrumed at 18 to such other fork. Pinion 17 meshes into a gear wheel 19 fast on the face of one blade 10 and concentric to the eye thereof.- ln order to insure a reliable con nection between gear wheel 19 and blade 10, the former is provided with .a squared boss 20 sunk into a corresponding opening of the blade. Rack 16 is provided with a stop 21 that limits the angle to which handles 13 may be operated. A guide 22 within each fork'12 engages the outer edge of segment 16' passing through such fork.

The correlation of the parts issuch that while rack 16 of one fork extends in one direction over the outer face of the first ,blade 10, rack 16of the second fork extends in the opposite direction over the outer face of the second blade, (dotted lines, Fig. 1). When handles 13' are closed, racks 16 will, by pinions 17 and gear wheels 19, simultaneously rotate blades 10 in opposite directions, while when the handles are opened, the rotation of the blades is reversed, as will be readily understood. Thus by manipulating the handles, the protruding parts of the hedges projecting between the points ofthe stellated.

blades 10, will be severed in large numbers vand with great rapidity.

l claim:

. 1. A hedge trimmer comprising a pair efV stellated cutting blades, a spindle on which l said blades are rotatable, a pair of handles turning onfthe spindle, and -means actuated by the handles for simultaneously rotating the blades in opposite directions, substantially as specified.

2. A hedge trimmer comprising a pair or stellated cutting blades, a spindle on which said blades are rotatable, a air of forked handles turning on the s ind e, and means actuated by the handles or simultaneously rotating the blades in opposite directions, substantially as specified.

3. A hedge trimmer comprising a pair of cutting blades, a commonspindle therefor, a pair of forked handles turning on the spindle, a curved rack Aand a pinion on each of the handles, the rack of one handle engaging the pinion of the other handle, and means for o era-tively connecting the pinions to `the b ades, substantially' as specified.

4. A hedge trimmer comprising a pair of cutting blades, a common spindle therefor, a pair of 'forked handles turning on the spindle, a fcurved rack and a pinion on each of the handles, the rack of one handle engaging thepiniont of the other handle, and gear wheels fast on the Vblades and engaged by the pinions, substantially asspecified.

5. A hedge trimmer comprising a pair of cutting blades, a common spindle therefor, a pair of forked handles turning on the spindle, a curved rack, a pinion and a guide on each of the handles, the rack of one handle engaging the pinion and guide of the other handle, and means for operatively connecting the pinions to the blades, substantially asspecitied.

Signed by me at New York city, (Manhattan,)-N. Y., this 12th day of September, 1907.
